UNITED STATES TORQUIL CAMPBELL, OF VANCOUVER, BRITISH COLUMBIA, CANADA.

GRAIN-DOOR.

Specification of Letters Patent.

Patented May 24, 1921.

Application filed January 21,1920. Serial No. 353,055.

7 '0 all whom it may concern Be it known that I, TORQUIL CAMPBELL, a subject of the King of Great Britain, and a resident of the city of Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Im provements in Grain-Doors, of which the following is a specification.

My invention relates to improvements in grain doors, and the object of my invention is to devise a door for grain cars which is simple in construction and operation, which is inexpensive to manufacture andinstall, and which is highly practical and eflicient.

I attain this object by the construction illustrated in the accompanying drawings in which- Figure 1 is a side elevation of a portion of a grain car showing the door in place.

Fig. 2 is a plan view of the door.

Fig. 3 is a view looking on the inside of the door.

Fig. 4 is a fragmentary perspective view of the door locking means.

Fig. 5 is a fragmentary sectional View showing the hinged flap.

Similar figures of reference indicate similar parts throughoutthe several views.

1 indicates the grain door, which is adapted to fit at its opposite ends in grooves 2 and 8 formed in the vertical posts 4 and 5 which form the sides of the door opening 6. The bottom of the door is cut out to form an opening 7 which opening is provided with a closure flap 8 hingedly connected to the upper edge ofthe opening, as at 9, so as to be swingable outwardly to open the opening 7 at will, and the lower edge of the flap is provided with a reinforcing angle bar 10, (or if preferred, a hinge member may be employed), through which bar a screw 11 is passed into thecar structure to lock the flap when closed, which screw may be readily withdrawn, however, when it is desired to raise the flap.

In order to enable the door to be opened a portion of the inner wall of the groove 2 is made as a separate piece, indicated by the numeral 12, extending from a point in alinement with the upper edge of the opening 7 to or above the upper edge of the door 1, and this piece 12 is hinged to the post 4, as at 13, so that it may be swung outwardly, as indicated in Fig. 4, from its normal closed position, as indicated in Fig. 2, when it is desired to open the door. The hinged portion 12 may be locked when closed by any approved means. The door 1 may be made in one piece or a supplementary portion 14: may be slidably fitted in the slots 2 and 3 should it be desired to increase the height of the door.

The manner in which the door is used and operated may be briefly described as follows. When the car is loaded the door extends across the door opening 6, its opposite ends resting in the grooves 2 and 3, the flap 8 being then closed and also the hinged piece 12. To unload the car the flap 8 is opened and swung outwardly and upwardly so that the grain flows out through the opening 7, thus reducing the amount of grain in the car and relieving the pressure on the door and on the hinged piece 12. The door may then be raised until it comes into alinement with the hinged member 12 which is then unlocked and swung inwardly, thus enabling the door to be moved clear of the groove 2 and removed from place so that the discharging operation may be completed through the wide open doorway.

The replacement of the door is effected in the same simple manner, one end being placed in the groove 3 and the other end in the cut away portion of the groove 2, which portion is then closed by swingin the hinged piece 12 inwardly and looking it, the door being,of course, lowered into place. The flap 8 is then closed and locked by means of the screw 11 against inadvertent opening, after which the car is ready to be loaded again.

From the foregoing it will be seen that I have devised a door for grain cars which is extremely simple and .which is highly practical and of great utility.

What I claim as my invention is:

The combination with a car having a door opening, of grooved posts on each side of the opening, a door adapted to fit said grooves and held against inadvertent displacement when seated therein, said door having a discharge opening in its lower edge and a closure member for said opening, and a normally secured hinged member forming the side wall of one of said grooves the lower edge of which is above the lower edge of the door, said hinged member being capable of opening to permit the removal of the door when the latter is raised into alinement with the lower edge thereof.

Dated at Vancouver, B. (1., this 23rd day of December, 1919.
